What Is a 3-Bet in Poker? A 3-bet is the third bet in a poker sequence, in which a player re-raises after the initial pre-flop raise, or 2-bet. (The blind payment is the first bet in Texas Hold'em and Omaha.)

For example, suppose another player raises preflop, leaving you with the option to call, fold, or re-raise. If you choose to re-raise, that action is known as a 3-bet, and you are the 3-bettor in the hand.
